Remove the primary IP address from int vlan 1 and leave it as 192.168.1 227,

Is this a DSL connection or does it connect to a modem? I suspect the public IP address on int vlan 1 should be applied to a dialer interface (for ADSL) or a BVI if it's ethernet. You could do it with a second int vlan and then make whatever Fe port connects to the modem a member of the second VLAN.

Fast ethernetinterface 4 configuration is ok , but required static ip can't be signed to other interfaces even after creating vlan and try to sign it to other interface as 0 or 1 , if you can help by steps , If u check both attached config for old wrt120 and new 877 you will figure the little different which required to change on 877 ,thank u for replying
